BACKGROUND

Existing RNA-targeting CRISPR-Cas applications provide tools to degrade RNA or modulate RNA structure but do not, on their own enhance gene expression or increase translational protein control. Likewise, existing methods of enhancing and/or increasing gene expression, such as the delivery of messenger RNAs, prove to be technically challenging. Indeed, there are few known or well characterized methods to increase mRNA translation.

The vast majority of gene regulatory drugs have been designed to knockdown gene expression (i.e. siRNAs, miRNAs, anti-sense, etc.). Some methods exist to enhance gene expression, such as the delivery of mRNAs; however, therapeutic delivery of such large and charged RNA molecules is technically challenging, inefficient, and not particularly practical. Classical gene therapy approaches involve delivery of a gene product as viral-encoded products (e.g. AAV or lentivirus-packaged products); however, these methods suffer from not being able to accurately reproduce the correct alternatively spliced isoforms in the correct ratios. In addition, gene delivery can exclude important non-coding regulatory sequences. Other methods of regulating protein translation involve engineered RNA binding proteins which are not easily delivered to cells and can be highly immunogenic. Often, engineered RNA binding proteins require extensive engineering for each target RNA sequence and certain of these possess limits to their applicability. More problematically, the act of expression of certain of these types of engineered RNA binding proteins, when combined with translation initiation factor functions in a fusion protein context, could disrupt the stoichiometry of translation machinery maintained by the cell.

As such, there is a need to provide compositions and methods for recruiting translational pre-initiation complexes in a manner which overcomes gene therapy barriers and protein engineering challenges, thereby controlling translation in cells and in gene therapy techniques.

Translational Enhancement Via M7G Cap Recruitment

Translation initiation in mammalian cells starts with the binding of the 5′ methyl-7 guanosine (m7G) cap structure by Eukaryotic Initiation Factor 4E (EIF4E), which results in the nucleation of translational pre-initiation complexes on the adjacent 5′ untranslated region (5′UTR) of mRNA. The bound pre-initiation complexes then scan the 5′UTR unidirectionally (5′ to 3′) for suitable start codons (e.g., “AUG”) to prime and initiate translation. The 5′ m7G cap is an evolutionarily conserved modification of eukaryotic mRNA, and serves as a unique molecular module that recruits cellular proteins and mediates cap-related biological functions such as pre-mRNA processing, nuclear export, and cap-dependent protein synthesis.

Provided herein are compositions and methods for enhancing protein production by recruiting an m7G cap to an mRNA using a capped-sgRNA and a Cas polypeptide. In the compositions and methods provided herein, the bound pre-initiation complexes do not necessarily scan the 5′UTR unidirectionally 5′ to 3′.

In some aspects, provided herein is a complex comprising at least one Cas polypeptide or nucleic acid encoding the at least one Cas polypeptide, and at least one m7G capped single guide RNA (capped-sgRNA) or nucleic acid encoding the at least one capped-sgRNA, where the at least one capped-sgRNA is capable of targeting the at least one Cas polypeptide to a target sequence in an RNA molecule (e.g., an mRNA). In some embodiments, upon hybridization between the sgRNA and the target sequence, the m7G cap of the sgRNA is brought closer to a desired start codon in the target mRNA as compared to the endogenous m7G cap of the target mRNA. Also provided are methods of regulating translation of an mRNA in a cell, the method comprising contacting the cell with a nucleic acid comprising (a) a sequence encoding a at least one Cas polypeptide; and (b) a sequence encoding at least one capped-sgRNA comprising (i) an m7G cap; (ii) a spacer capable of specifically hybridizing with a target sequence in an RNA molecule; and (iii) a direct repeat capable of binding to the Cas polypeptide.

In some aspects, provided herein is a complex comprising a Cas polypeptide or nucleic acid encoding the Cas polypeptide, and an m7G capped single guide RNA (capped-sgRNA) or nucleic acid encoding the capped-sgRNA, where the capped-sgRNA is capable of targeting the Cas polypeptide to a target sequence in an RNA molecule (e.g., an mRNA). In some embodiments, upon hybridization between the sgRNA and the target sequence, the m7G cap of the sgRNA is brought closer to a desired start codon in the target mRNA as compared to the endogenous m7G cap of the target mRNA. Also provided are methods of regulating translation of an mRNA in a cell, the method comprising contacting the cell with a nucleic acid comprising (a) a sequence encoding a Cas polypeptide; and (b) a sequence encoding a capped-sgRNA comprising (i) an m7G cap; (ii) a spacer capable of specifically hybridizing with a target sequence in an RNA molecule; and (iii) a direct repeat capable of binding to the Cas polypeptide.

Each strand of DNA or RNA has a 5′ end and a 3′ end, corresponding to the carbon position on the deoxyribose (or ribose) ring. “Upstream” as described herein can mean toward the 5′ end of an RNA molecule and “downstream” as described herein can mean towards the 3′ end of an RNA molecule. A “start codon” as described herein can refer to the first codon of a messenger RNA transcript translated by a ribosome. The most common start codon is AUG. Alternative start codons from both prokaryotes and eukaryotes include, but not limited to, GUG, UUG, AUU, and CUG.

The term “cell” as used herein may refer to either a prokaryotic or eukaryotic cell, optionally obtained from a subject or a commercially available source.

The term “encode” as it is applied to nucleic acid sequences refers to a polynucleotide which is said to “encode” a polypeptide, an mRNA, or an effector RNA if, in its native state or when manipulated by methods well known to those skilled in the art, can be transcribed and/or translated to produce the effector RNA, the mRNA, or an mRNA that can for the polypeptide and/or a fragment thereof. The antisense strand is the complement of such a nucleic acid, and the encoding sequence can be deduced therefrom.

As used herein, the term “expression” or “gene expression” refers to the process by which polynucleotides are transcribed into mRNA and/or the process by which the transcribed mRNA is subsequently translated into peptides, polypeptides, or proteins. If the polynucleotide is derived from genomic DNA, expression may include splicing of the mRNA in a eukaryotic cell. The expression level of a gene may be determined by measuring the amount of mRNA or protein in a cell or tissue sample; further, the expression level of multiple genes can be determined to establish an expression profile for a particular sample.

The term “target sequence” can refer to a nucleic acid sequence present in an RNA molecule to which a spacer of a guide RNA (e.g, a capped-sgRNA as disclosed herein) can hybridize, provided sufficient conditions for hybridization exist. Hybridization between the spacer and the target sequence can, for example, be based on Watson-Crick base pairing rules, which enables programmability in the spacer sequence. The spacer sequence can be designed, for instance, to hybridize with any target sequence.

The “spacer” or “spacer sequence” is comprised within a single guide RNA can include a nucleotide sequence that is complementary to a specific sequence within a target RNA.

“Binding” as used herein can refer to a non-covalent interaction between macromolecules (e.g., between a protein and a nucleic acid). While in a state of non-covalent interaction, the macromolecules are said to be “associated” or “interacting” or “binding” (e.g., when a molecule X is said to interact with a molecule Y, it means that the molecule X binds to molecule Y in a non-covalent manner). Binding interactions are generally characterized by a dissociation constant (Kd) of less than 10⁻⁶ M, less than 10⁻⁷ M, less than 10⁻⁸ M, less than 10⁻⁹M, less than 10⁻¹⁰ M, less than 10⁻¹¹ M, less than 10⁻¹² M, less than 10⁻¹³ M, less than 10⁻¹⁴ M, or less than 10⁻¹⁵M. Kd is dependent on environmental conditions, e.g., pH and temperature, as is known by those in the art. “Affinity” can refer to the strength of binding, and increased binding affinity is correlated with a lower Kd.

The terms “hybridizing” or “hybridize” can refer to the pairing of substantially complementary or complementary nucleic acid sequences within two different molecules. Pairing can be achieved by any process in which a nucleic acid sequence joins with a partially, substantially or fully complementary sequence through base pairing to form a hybridization complex. For purposes of hybridization, two nucleic acid sequences or segments of sequences are “substantially complementary” if at least 80% of their individual bases are complementary to one another. Two nucleic acid sequences or segments of sequences are “partially complementary” if at least 50% of their individual bases are complementary to one another.

As used herein, “complementary” can mean that two nucleic acid sequences have at least 50% sequence identity. Preferably, the two nucleic acid sequences have at least 60%, 70%, 80%, 90%, 95%, 96%, 97%, 98%, 99%, or 100% of sequence identity. “Complementary” also means that two nucleic acid sequences can hybridize under low, middle, and/or high stringency condition(s).

As used herein, “substantially complementary” means that two nucleic acid sequences have at least 90% sequence identity. Preferably, the two nucleic acid sequences have at least 95%, 96%, 97%, 98%, 99%, or 100% of sequence identity. “Substantially complementary” can also mean that two nucleic acid sequences can hybridize under high stringency condition(s).

Low stringency hybridization refers to conditions equivalent to hybridization in 10% formamide, 5×Denhardt's solution, 6×SSPE, 0.2% SDS at 22° C., followed by washing in 1×SSPE, 0.2% SDS, at 37° C. Denhardt's solution contains 1% Ficoll, 1% polyvinylpyrolidone, and 1% bovine serum albumin (BSA). 20×SSPE (sodium chloride, sodium phosphate, ethylene diamide tetraacetic acid (EDTA)) contains 3M sodium chloride, 0.2M sodium phosphate, and 0.025 M (EDTA). Other suitable moderate stringency and high stringency hybridization buffers and conditions are well known to those of skill in the art.

As used herein, “operably linked” refers to the situation in which part of a linear DNA sequence can influence the other parts of the same DNA molecule. For example, when a promoter controls the transcription of the coding sequence, it is operatively linked to the coding sequence.

As used herein, a “polypeptide” refers to, without limitation, proteins, fragments of proteins, and peptides, whether isolated from natural sources, produced by recombinant techniques, or chemically synthesized. A polypeptide may have one or more modifications, such as a post-translational modification (such as glycosylation, etc.) or any other modification (such as PEGylation, etc.). The polypeptide may contain one or more non-naturally-occurring amino acids (such as an amino acid with a side chain modification). Polypeptides described herein typically comprise at least about 10 amino acids.

As used herein, “contacting” a cell with a nucleic acid molecule can include allowing the nucleic acid molecule to be in sufficient proximity with the cell such that the nucleic acid molecule can be introduced into the cell.

A “promoter” can be a region of DNA that leads to initiation of transcription of a gene.

As used herein, “nuclease-deficient” may refer to a polypeptide with reduced nuclease activity, reduced endo- or exo-DNAse activity or RNAse activity, reduced nickase activity, or reduced ability to cleave DNA and/or RNA. “Reduced nuclease activity” means a decline in nuclease, nickase, DNAse, or RNAse activity of at least about 1%, 2%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 35%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 100% or more or any value between any of the listed values. Alternatively, “reduced nuclease activity” may refer to a decline of at least about 1-fold, 1.5-fold, 2-fold, 3-fold, 4-fold, 5-fold, 6-fold, 7-fold, 8-fold, 9-fold, 10-fold, 15-fold, 20-fold, 30-fold, 40-fold, 50-fold, 60-fold, 70-fold, 80-fold, 90-fold, 100-fold, 500-fold, 1000-fold, 2000-fold or more or any value between any of the listed values.

“Nucleic acids” may be naturally occurring nucleic acids such as DNA and RNA, or artificial nucleic acids including peptide nucleic acid (PNA), morpholino, locked nucleic acid (LNA), glycol nucleic acid (GNA), and threose nucleic acid (TNA).

I. m7G Cap

The m7G cap, or 7-methylguanosine cap, is a guanine nucleotide methylated on the 7 position and can be linked to an RNA molecule (e.g., a sgRNA or an mRNA) via a 5′ to 5′ triphosphate linkage. In one embodiment, capped RNA molecules (e.g., capped-sgRNAs) disclosed herein include a single methyl group on the terminal G residue at the N-7 position. In vivo, the m7G cap structure is added enzymatically to mRNA produced by RNA polymerase II. In one embodiment, the adjacent nucleotides can be 2′-O-methylated to different extents. For example, the m7G cap can be a m7GpppN, or Cap 0, an m7GpppNm, or Cap 1, and an m7GpppNmpNm, or Cap 2. Exemplary structures of Cap 0 and Cap 1, are shown below:

The 5′ m7G cap is an evolutionarily conserved modification of eukaryotic mRNA, and serves as a unique molecular module that recruits cellular proteins and mediates cap-related biological functions such as pre-mRNA processing, nuclear export, and cap-dependent protein synthesis. The capped-sgRNA disclosed herein exploits these biological functions to recruit pre-initiation complexes for enhancement of protein translation.

The capped-sgRNA disclosed herein includes a nucleic acid sequence which is transcribed by, e.g. an RNA polymerase II, and the sgRNA thereby becomes 5′ capped upon transcription with an m7G cap. The transcription of capped-sgRNA nucleic acid sequence is catalyzed by bacteriophage RNA polymerases, such as, without limitation, RNA polymerase T7, T3, and SP6. When bacteriophage RNA polymerases are used to generate the sgRNAs of the present disclosure, cap analogs initiate transcription. In one embodiment, the m7G(5′)pppG cap analog is incorporated into the sgRNA and simulates the m7G cap structure. In another embodiment, standard cap analogs are incorporated into the sgRNA in the forward (e.g., [m7G(5′)pppG(pN)]) or the reverse orientation (e.g., [G(5′)pppm7G(pN)]) resulting in two forms of isomeric RNAs. In another embodiment, chemical modifications at either the 2′ or 3′ OH group results in the cap being incorporated solely in the forward orientation. In some embodiments, the m7G cap is an anti-reverse cap analog (ARCA), wherein one of the 3′ OH groups (closer m7G) is eliminated from the cap analog and is substituted with —OCH₃. This modification forces RNA polymerases to initiate transcription with the remaining —OH group in G and thus synthesize RNA transcripts capped exclusively in the correct orientation. An exemplary structure of ARCA (m7(3′-O-methyl)-G(5′)ppp(5′)G) is shown below:

Additional cap analogs contemplated herein also include unmethylated cap analogs (e.g., GpppG), trimethylated cap analogs (e.g., m₃ ^(2.2.7)GP₃G), and m₂ ^(7,3′-O)GP₃(2′OMe)ApG.

In one embodiment, the m7G cap disclosed herein includes chemical modifications relative to the naturally occurring m7G cap. For example, chemical modifications that can reduce the sensitivity of the m7G cap to cellular decapping enzymes are useful for the capped-RNAs disclosed herein. Suitable chemical modifications include, without limitation, those with 1,2-dithiodiphosphate. See those described in e.g., Strenkowska et al., Nucleic Acids Res. 44(20):9578-9590 (2016), phosphate-modified cap analogues described in e.g., Walczak et al., Chem Sci. 8(1):260-267 (2017)), as well as those described in Basolo et al., Eur J Endocrinol., 145(5):599-604 (2001), and Borghardt et al., Can Respir J. 2018 Jun. 19; 2018:2732017, all of which are incorporated herein by reference in their entirety.

In some embodiments, the guide RNA or a portion thereof does not comprise a sequence complementary to a PFS.

Target RNA

The “target sequence” can be a stretch of nucleic acid sequences or a sequence motif present in an RNA molecule (e.g., mRNA) of interest to which a spacer sequence of the capped-sgRNA hybridizes, provided sufficient conditions for hybridization exist. Hybridization between the spacer and the target sequence is, for example, based on Watson-Crick base pairing rules, which enables programmability of the spacer sequence.

In one embodiment, the mRNA including the target sequence additionally includes one or more start codons and/or an endogenous m7G cap. In another embodiment, the target sequence is located downstream of an endogenous m7G cap, with its 5′ end located either upstream or downstream of a desired start codon. Any start codon in the target mRNA can be selected as the desired start codon. Upon hybridization between the spacer sequence of the capped-sgRNA and the target sequence, the m7G cap of the capped-sgRNA can be recruited to the vicinity of the desired start codon, and closer in proximity to the desired start codon than the endogenous m7G cap of the mRNA. In one embodiment, the m7G cap of the bound capped-sgRNA recruits translation initiation factors (e.g., EIF4E) and initiates protein translation from the desired start codon. In another embodiment, recruitment of the translation initiation factors occurs subsequent to the binding of the m7G cap of the capped-sgRNA. Without wishing to be bound by theory, the recruitment of an m7G cap via a capped-sgRNA to the vicinity of a desired start codon in a transcript allows for enhanced protein translation, as compared to protein translation initiated by the endogenous m7G cap of the transcript.

In one embodiment, the target sequence includes the desired start codon of the target mRNA. For example, the 5′ end of the target sequence can be upstream of the desired start codon and the 3′ end of the target sequence can be downstream of the desired start codon. In one embodiment, the 5′ end of the target sequence is located between 1 and 50 nucleotides (e.g., about 49, 48, 47, 46, 45, 44, 43, 42, 41, 40, 39, 38, 37, 36, 35, 34, 33, 32, 31, 30, 29, 28, 27, 26, 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, or 2 nucleotides) upstream of the first nucleotide of the desired start codon (e.g., an “A”). In another embodiment, the 5′ end of the target sequence is located between 1 and 50 nucleotides (e.g., about 49, 48, 47, 46, 45, 44, 43, 42, 41, 40, 39, 38, 37, 36, 35, 34, 33, 32, 31, 30, 29, 28, 27, 26, 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, or 2 nucleotides) downstream of the last nucleotide of the desired start codon. In some embodiments, the target sequence does not overlap with the desired start codon. The location ranges of the target sequence between about 1 and 50 nucleotides upstream or downstream of the desired start codon accounts for the differing structural properties of the various Cas proteins capable of being used with the capped-sgRNAs disclosed herein. In another embodiment, the target sequence is not required to be located between 1 and 50 nucleotides upstream or downstream from a desired start codon, rather the target sequence is located anywhere on the transcript. This is particularly relevant if the 5′UTR is large.

Direct Repeat/Scaffold

The capped-sgRNA disclosed herein includes both a “spacer sequence” and a “direct repeat” (or “DR” or “direct repeat sequence” or “DR sequence”). In one embodiment, DR is comprised within a scaffold sequence which is capable of binding to a corresponding (or cognate) Cas polypeptide. In another embodiment, a DR is capable of binding to a corresponding (or cognate) Cas polypeptide. A direct repeat sequence disclosed herein is a repetitive sequence found within a CRISPR locus (naturally-occurring in a bacterial genome or plasmid). It is well known that one would be able to infer the DR sequence of a corresponding Cas protein if the sequence of the associated CRISPR locus is known.

Generally, a DR is a nucleic acid sequence that consists of two or more repeats of a specific sequence, i.e., nucleotide sequences present in multiple copies in the genome. A DR sequence may or may not have intervening nucleotides. In one embodiment, a DR sequence disclosed herein includes about 10 to about 100 nucleotides (e.g. about 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, or 98 nucleotides). In another embodiment, the DR sequence is orientated either 5′ or 3′ to a spacer within the sgRNA. In one embodiment, the direct repeat sequence is located 5′ to the spacer. In another embodiment, the DR sequence is located 3′ to the spacer.

Scaffold/DR sequences of the disclosure bind the CRISPR/Cas RNA-binding protein of the disclosure. Scaffold/DR sequences of the disclosure may include a trans acting RNA (tracrRNA). Upon binding to a target sequence of an RNA molecule, the scaffold/DR sequence guides a fusion protein to the RNA molecule. In some embodiments, a scaffold/DR sequence having sufficient complementarity to a target sequence of an RNA molecule to bind selectively (partially or substantially) to the target sequence has at least 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96, 97%, 98%, 99%, or any percentage identity in between to the target sequence. In some embodiments, a scaffold/DR sequence having sufficient complementarity to a target sequence of an RNA molecule to bind selectively to the target sequence has 100% identity the target sequence. In some embodiments, scaffold/DR sequences of the disclosure comprise a secondary structure or a tertiary structure. Exemplary secondary structures include, but are not limited to, a helix, a stem loop, a bulge, a tetraloop and a pseudo not. Exemplary tertiary structures include, but are not limited to, an A-form of a helix, a B-form of a helix, and a Z-form of a helix. Exemplary tertiary structures include, but are not limited to, a twisted or helicized stem loop. Exemplary tertiary structures include, but are not limited to, a twisted or helicized pseudoknot. In some embodiments, scaffold/DR sequences of the disclosure comprise at least one secondary structure or at least one tertiary structure. In some embodiments, scaffold/DR sequences of the disclosure include one or more secondary structure(s) or one or more tertiary structure(s).

Linker

The capped-sgRNA disclosed herein can include a “linker” or “linker sequence” between the m7G cap or analog thereof and the spacer and/or DR sequences. In one embodiment, the linker sequence includes about 5 to about 25 nucleotides (e.g., about 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, or 24 nucleotides). In another embodiment, the linker sequence is non-complementary to any sequence within the RNA molecule comprising the target sequence. Exemplary sequences for such a linker include, without limitation: GTCAGATCG (SEQ ID NO: 306), GTCAGATCGCCT (SEQ ID NO: 307), GTCAGATCGCCTGGA (SEQ ID NO: 308), and GTCAGATCGCCTGGAATT (SEQ ID NO: 309). Any suitable linker sequences known in the art are also contemplated herein. In some embodiments, the linker sequence is modified to adjust the editing window.

RNase P Processing Site

Some embodiments provide a nucleic acid encoding the capped-sgRNA described herein, where an unprocessed capped-sgRNA is first generated upon transcription of the nucleic acid. In one embodiment, an unprocessed capped-sgRNA includes an RNase P processing site, which is downstream of the spacer and/or direct repeat and upstream of a poly-A tail. In this manner, an RNase P binds to the processing site and removes the downstream sequence (e.g., the poly-A tail) to generate a capped-sgRNA disclosed herein. Exemplary RNase P processing sites can be found at Esakova and Krasilnikov, RNA 16:1725-1747, 2010 (e.g., See FIG. 1 of Esakova and Krasilnikov), incorporated herein by reference in its entirety. The RNase P processing site is known to include elements recognizable by RNase P, such as those described in Kirseborn et al. Biochimie 89: 1183-1194, 2007 and Lai et al. FEBS Left 584: 287-296, 2010, both of which are incorporated herein by reference in their entirety. For example, the RNase P processing site can include all or a portion of a bacterial (e.g., E. coli) pre-tRNA, 4.5S rRNA precursor, or yeast pre-rRNA that includes an RNase cleavage site. Structures that resemble tmRNA, operon mRNAs, phage RNAs, OLE RNA from extremophilic bacteria are also contemplated herein as RNase P processing sites. All or a portion of a viral non-tRNA such as TYMV RNA are also useful as RNase P processing sites. In some embodiments, an RNase P processing site includes a tRNA-like small RNA (e.g., GenBank Accession No. FJ209302).

An exemplary structure of an unprocessed capped-sgRNA is shown in FIG. 1B. In this embodiment, the unprocessed capped-sgRNA includes from 5′ to 3′: an m7G cap, a linker, a spacer, a direct repeat, an RNase P processing site, and a poly-A tail. In another embodiment, the RNase P processing site and poly-A tail is removed upon RNase P processing, thereby generating the capped-sgRNA with the structure of FIG. 1C, wherein a′ is a guanosine or adenine, b′ is a spacer sequence and c′ is a direct repeat sequence.

III. CRISPR/Cas Polypeptides

The capped-sgRNAs disclosed herein are capable of binding with their cognate or corresponding RNA-binding CRISPR/Cas polypeptides (e.g., via a direct repeat sequence in the capped-sgRNA). In one embodiment, the capped-sgRNA includes a spacer sequence that confers target specificity to the Cas/sgRNA complex. CRISPR/Cas polypeptides are well known in the art and any particular Cas polypeptide can be adapted for use in the capped-sgRNA systems disclosed herein. In some embodiments, the Cas polypeptides for use as disclosed herein have altered activity compared to its corresponding wild type Cas polypeptide. In some embodiments, the Cas polypeptides are nuclease-deficient Cas (dCas) polypeptides. Nuclease-deficient Cas polypeptides have altered (e.g., diminished or abolished) nuclease activity without substantially diminished binding affinity to the sgRNA. These Cas polypeptides are useful, for example, in mediating the direct association between the capped-sgRNA and the target mRNA, and in protecting the 3′ end of the capped-sgRNA from degradation. In some embodiments, the dCas for use with the capped-sgRNA disclosed herein is devoid of cleavage activity that is applicable to the target RNA. In some embodiments, the dCas polypeptide for use with the capped-sgRNA disclosed herein retains cleavage activity that is applicable to the capped-sgRNA. In some embodiments, the dCas13 comprises an inactivated target cleavage domain and a retained or partially retained (i.e., activated or partially activated) guide cleavage domain.

In one embodiment, the Cas polypeptide is Cas13b. In another embodiment, the Cas polypeptide is dead or nuclease deficient Cas13b (dCas13b). In another embodiment, the dCas13b comprises an inactivated target cleavage domain and a retained (i.e., activated) guide cleavage domain as exemplified in FIGS. 1B and 1D. In one embodiment, the Cas polypeptide disclosed herein is a Type II CRISPR Cas protein. In some embodiments, the Type II CRISPR Cas protein includes a Cas9 protein. Exemplary Cas9 proteins of the disclosure may be isolated or derived from any species, including, but not limited to, bacteria or archaea. Exemplary Cas9 proteins of the disclosure may be isolated or derived from any species, including, but not limited to, Streptococcus pyogenes, Haloferax mediteranii, Mycobacterium tuberculosis, Francisella tularensis subsp. novicida, Pasteurella multocida, Neisseria meningitidis, Campylobacter jejune, Streptococcus thermophilus, Campylobacter lari CF89-12, Mycoplasma gallisepticum str. F, Nitratifractor salsuginis str. DSM 16511, Parvibaculum lavamentivorans, Roseburia intestinalis, Neisseria cinerea, a Gluconacetobacter diazotrophicus, an Azospirillum B510, a Sphaerochaeta globus str. Buddy, Flavobacterium columnare, Fluviicola taffensis, Bacteroides coprophilus, Mycoplasma mobile, Lactobacillus farciminis, Streptococcus pasteurianus, Lactobacillus johnsonii, Staphylococcus pseudintermedius, Filifactor alocis, Treponema denticola, Legionella pneumophila str. Paris, Sutterella wadsworthensis, Corynebacter diphtherias, Streptococcus aureus, and Francisella novicida.

Some embodiments of the capped-sgRNA compositions or methods disclosed herein provide a Cas9 polypeptide. In certain embodiments, the Cas9 polypeptide lacks part or all of the nuclease domains (e.g., the RuvC and/or HNH domains) of a wild type Cas9 polypeptide, and therefore are nuclease-deficient. These truncated Cas9 polypeptides have a smaller size as compared to a wild type Cas9. The RuvC and HNH nuclease domains can also be inactivated, for example, as a result of point mutations within these domains. For instance, D10A and H840A mutations in Streptococcus pyogenes Cas9 (SpCas9) results in nuclease-deficient SpCas9. An exemplary sequence of a nuclease-deficient SpCas9 is SEQ ID NO: 310. The RuvC domain is distributed among 3 non-contiguous portions of the nuclease-deficient Cas9 primary structure (residues 1-60, 719-775, and 910-1099). The HNH domain is composed of residues 776-909.

Paris, Sutterella wadsworthensis, Corynebacter diphtheriae, Streptococcus aureus, and Francisella novicida.

Any Cas polypeptides with altered nuclease activity as compared to a naturally occurring Cas polypeptide is contemplated herein. Additional types of nuclease-deficient Cas polypeptides are described in e.g., Brezgin et al. Int J Mol Sci 20(23):6041, 2019 and Xu and Lei, J Mol Biol 431:34-47, 2019, incorporated by reference in its entirety.

Exemplary Cas polypeptide sequences disclosed in the methods for translational enhancement WO2019/204828 are incorporated herein by reference in their entirety and can be used in conjunction with the corresponding capped-sgRNAs disclosed herein.

In some embodiments of the compositions of the disclosure, the CRISPR Cas protein comprises a Type V CRISPR Cas protein. In some embodiments, the Type V CRISPR Cas protein comprises a Cpf1 protein. Exemplary Cpf1 proteins of the disclosure may be isolated or derived from any species, including but not limited to, bacteria or archaea. Exemplary Cpf1 proteins of the disclosure may be isolated or derived from any species, including but not limited to, Francisella tularensis subsp. novicida, Acidaminococcus sp. BV3L6 and Lachnospiraceae bacterium sp. ND2006. Exemplary Cpf1 proteins of the disclosure may be nuclease inactivated.

In some embodiments, the CRISPR Cas protein comprises a Type VI CRISPR Cas protein or portion thereof. In some embodiments, the Type VI CRISPR Cas protein comprises a Cas13 protein or portion thereof. Exemplary Cas13 proteins of the disclosure may be isolated or derived from any species, including, but not limited to, bacteria or archaea. Exemplary Cas13 proteins of the disclosure may be isolated or derived from any species, including, but not limited to, Leptotrichia wadei, Listeria seeligeri serovar 1/2b (strain ATCC 35967/DSM 20751/CIP 100100/SLCC 3954), Lachnospiraceae bacterium, Clostridium aminophilum DSM 10710, Carnobacterium gallinarum DSM 4847, Paludibacter propionicigenes WB4, Listeria weihenstephanensis FSL R9-0317, Listeria weihenstephanensis FSL R9-0317, bacterium FSL M6-0635 (Listeria newyorkensis), Leptotrichia wadei F0279, Rhodobacter capsulatus SB 1003, Rhodobacter capsulatus R121, Rhodobacter capsulatus DE442 and Corynebacterium ulcerans. Exemplary Cas13 proteins of the disclosure may be DNA nuclease inactivated. Exemplary Cas13 proteins of the disclosure include, but are not limited to, Cas13a, Cas13b, Cas13c, Cas13d, and orthologs thereof. Exemplary Cas13b proteins of the disclosure include, but are not limited to, subtypes 1 and 2 referred to herein as Csx27 and Csx28, respectively.

In some embodiments of the compositions of the disclosure, the sequence encoding the RNA binding protein comprises a sequence isolated or derived from a Cas13d protein or also called CasRx/Cas13d proteins. CasRX/Cas13d is an effector of the type VI-D CRISPR-Cas systems. In some embodiments, the CasRX/Cas13d protein is an RNA-guided RNA endonuclease enzyme that can cut or bind RNA. In some embodiments, the CasRX/Cas13d protein can include one or more higher eukaryotes and prokaryotes nucleotide-binding (HEPN) domains. In some embodiments, the CasRX/Cas13d protein can include either a wild-type or mutated HEPN domain. In some embodiments, the CasRX/Cas13d protein includes a mutated HEPN domain that cannot cut RNA but can process guide RNA. In some embodiments, the CasRX/Cas13d protein does not require a protospacer flanking sequence. Also see WO Publication No. WO2019/040664 & US2019/0062724, which is incorporated herein by reference in its entirety, for further examples and sequences of CasRX/Cas13d protein.

In some instances, the Cas polypeptide has a sequence that is at least 80% identical (e.g. at least 82%, 84%, 86%, 88%, 90%, 92%, 94%, 96%, 98%, or 99% identical) to any of the Cas polypeptides (e.g., any of the wild type or nuclease-deficient Cas polypeptides) of the present disclosure.

IV. Nucleic Acids Encoding the Capped-sgRNA and/or the Cas Polypeptide

Some embodiments disclosed herein provide compositions comprising a nucleic acid sequence encoding the capped-sgRNAs described herein, and vectors (e.g., expression vector(s)) comprising the nucleic acid sequences. In some embodiments, nucleic acid sequences encoding the capped-sgRNAs are operably linked to one or more promoters. Suitable promoters include, without limitation, RNA polymerase II promoters such as, without limitation, CMV, PGK, and EF1α promoters. In one embodiment, the RNA polymerase II promoter is an RNA Pol II transcribed non-coding RNA. The sgRNA is transcribed by the RNAase polymerase II, acquires an m7G cap and becomes polyadenylated. Additional promoters suitable for driving expression of the capped-sgRNA are also contemplated, such as, without limitation, bacteriophage promoters (e.g., RNA polymerase T3, T7, and SP6), ubiquitous promoters, tissue-specific promoters, inducible promoters, and constitutive promoters. For example, liver-specific promoters as described in PCT/US06/00668 are contemplated herein. For example, promoters for genes encoding genes encoding c-jun; jun-b; c-fos; c-myc; serum amyloid A; apolipoprotein B editing catalytic subunit; liver regeneration factors, such as LRF-I; signal transducers; activators of transcription, such as STAT-3; serum alkaline phosphates (SAP); insulin-like growth factor-binding proteins, such as IGFBP-I; cyclin D1; active protein-1; CCAAT enhancer core binding protein; ornithine decarboxylase; phosphatase of regenerating liver-1; early growth response gene-1; hepatocyte growth factors; hemopexin; insulin-like growth factors (IGF), such as IGF-I and IGF-2; hepatocyte nuclear family 1; hepatocyte nuclear family 4; hepatocyte Arg-Ser-rich domain-containing proteins; glucose 6-phosphatase; acute phase proteins, such as serum amyloid A and serum amyloid P (SAA/SAP); steroid hydroxylases; leukotriene hydroxylases; fatty acid hydroxylases; desmolase; peptidyl isomerases; and sterol demethylases.

In one embodiment, vectors comprising the nucleic acids that encode the capped-sgRNA further include a sequence that encodes a Cas polypeptide (e.g., any of the Cas polypeptides described herein, such as, without limitation, a truncated nuclease-deficient Cas protein). The capped-sgRNA and the Cas transcript can be transcribed from the same promoter, or from different promoters. RNA polymerase II promoters (e.g. CMV, PGK, and EF1α promoters), for example, are suitable for driving expression of both the sgRNA and the Cas gene. In some embodiments, the Cas transcript is expressed from one promoter, such as a PGK promoter, and the capped-sgRNA is expressed from a different promoter, such as an EF1α promoter.

Some embodiments disclosed herein provide nucleic acids encoding the Cas polypeptides and vectors comprising the nucleic acids that encode the Cas polypeptides. Nucleic acids encoding the Cas polypeptides can be operably linked to one or more promoters. Suitable promoters include RNA polymerase II promoters (e.g., CMV, PGK, and EF1α promoters), bacteriophage promoters (e.g., RNA polymerase T3, T7, and SP6), ubiquitous promoters, tissue-specific promoters, inducible promoters, and constitutive promoters. The Cas polypeptide can be associated with or include or be in operable linkage with a tag or detectable agent, such as a fluorescent agent, a fluorescent protein, an enzyme.

In some embodiments, a sequence encoding a capped-guide RNA of the disclosure includes a sequence encoding a promoter to drive expression of the guide RNA. In some embodiments, a vector that includes a sequence encoding a capped-guide RNA of the disclosure includes a sequence encoding a promoter to drive expression of the guide RNA. In some embodiments, a promoter driving expression of the guide RNA includes a sequence encoding a constitutive promoter, or an inducible promoter. In some embodiments, a promoter to drive expression of the guide RNA includes a sequence encoding a hybrid or a recombinant promoter. In some embodiments, a promoter to drive expression of the guide RNA is a promoter capable of expressing the guide RNA in a mammalian cell or a human cell. In some embodiments, a promoter to drive expression of the guide RNA is a promoter capable of expressing the guide RNA and restricting the guide RNA to the nucleus of the cell. In some embodiments, a promoter to drive expression of the guide is a human RNA polymerase promoter or a sequence isolated or derived from a human RNA polymerase promoter. In some embodiments, a promoter to drive expression of the guide RNA is a U6 promoter or a sequence isolated or derived from a U6 promoter. In some embodiments, a promoter to drive expression of the guide RNA is a human tRNA promoter or a sequence isolated or derived from a human tRNA promoter. In some embodiments, a promoter to drive expression of the guide RNA is a human valine tRNA promoter or a sequence isolated or derived from a human valine tRNA promoter.

In some embodiments of the compositions of the disclosure, a promoter to drive expression of the capped-guide RNA further includes a regulatory element. In some embodiments, a vector that includes promoter to drive expression of the guide RNA further includes a regulatory element. In some embodiments, a regulatory element enhances expression of the guide RNA. Exemplary regulatory elements include, but are not limited to, an enhancer element, an intron, an exon, or a combination thereof.

In some embodiments, the nucleic acid sequences encoding the Cas polypeptides are linked to one or more localization signals. Localization signals are amino acid sequences on a protein that tags the protein for transportation to a particular location in a cell. An exemplary localization signal is a nuclear localization signal (NLS), which is an amino acid sequence that tags a protein for import into the cell nucleus by nuclear transport. In one embodiment, one or more localization signals is/are operably linked to the sequence encoding a Cas polypeptide. In some embodiments, the localization signal is a nuclear localization signal (NLS). An exemplary NLS is SV40 large T antigen NLS (PKKKRRV (SEQ ID NO: 477)) and nucleoplasmin NLS (KRPAATKKAGQAKKKK (SEQ ID NO: 478)). Other NLSs are known in the art; see, e.g., Konermann et al., Cell 173:665-676, 2018; Cokol et al., EMBO Rep. 1(5):411-415 (2000); Freitas and Cunha, Curr Genomics 10(8): 550-557 (2009), incorporated herein by reference in their entirety. Without limitation, additional NLSs are those that have K(K/R)X(K/R) as a putative consensus sequence (e.g., PAAKRVKLD (SEQ ID NO: 479)). Other additional NLSs include KRSWSMAF (SEQ ID NO: 480) and KRKYF (SEQ ID NO: 481). In some embodiments, vectors comprising the nucleic acids that encode the Cas polypeptide further encode a capped-sgRNA (e.g., any of the capped-sgRNAs described herein). In some embodiments, the localization signal is a nuclear export signal (NES). Incorporating an NES is particularly suited for altering molecular machinery in the cytoplasm. In one embodiment, an NES is the HIV-REV NES or the PKI NES.

In other embodiments, the nucleic acids encoding the capped-sgRNA and/or the Cas polypeptide can be further operably linked to a sequence that encodes one or more reporter genes, or effector genes such as, without limitation, endonucleases that have nuclease activity. In one embodiment, a nucleic acid sequence encodes a capped-sgRNA disclosed herein and a fusion protein that includes a dCas polypeptide and an endonuclease. Any suitable reporter genes are contemplated, including but not limited to, fluorescent reporters. In addition, any suitable endonucleases are contemplated for fusing with a Cas polypeptide, in particular a dCas polypeptide.

V. Vectors

Vectors contemplated for the present disclosure can include those that are suitable for expression in a selected host, whether prokaryotic or eukaryotic, for example, phage, plasmid, and viral vectors. Viral vectors may be either replication competent or replication defective retroviral vectors. Viral propagation generally will occur only in complementing host cells comprising replication defective vectors, for example, when using replication defective retroviral vectors in methods provided herein viral replication will not occur. Vectors may comprise kozak sequences (Lodish et al., Molecular Cell Biology, 4th ed., 1999) and may also contain the ATG start codon. Promoters that function in a eukaryotic host are from, without limitation, SV40, LTR, CMV, EF-1 a, white cloud mountain minnow β-actin.

In some embodiments of the compositions of the disclosure, a vector of the disclosure includes one or more of a sequence encoding at least one capped-guide RNA of the disclosure, one or more promoters to drive expression of the one or more guide RNAs and a sequence encoding a regulatory element. In some embodiments of the compositions of the disclosure, the vector further includes a sequence encoding a Cas polypeptide, a dCas polypeptide or a dCas-fusion protein.

Copy number and positional effects are considered in designing transiently and stably expressed vectors. Copy number can be increased by, for example, dihydrofolate reductase amplification. Positional effects can be optimized by, for example, Chinese hamster elongation factor-1 vector pDEF38 (CHEF1), ubiquitous chromatin opening elements (UCOE), scaffold/matrix-attached region of human (S/MAR), and artificial chromosome expression (ACE) vectors, as well as by using site-specific integration methods known in the art. The expression constructs containing the vector can further contain sites for transcription initiation, termination, and, in the transcribed region, a ribosome binding site for translation. The coding portion of the transcripts expressed by the constructs can include a translation initiating codon at the beginning and a termination codon (UAA, UGA, or UAG) appropriately positioned at the end of the polypeptide to be translated.

Considering the above-mentioned factors, exemplary vectors suitable for expressing Cas polypeptides and/or sgRNAs in bacteria include PiggyBac transposon vectors, pTT vectors (e.g., from Biotechnology Research Institute (Montreal, Canada)), pQE70, pQE60, and pQE-9 (e.g. those available from Qiagen (Mississauga, Ontario, Canada)); vectors derived from pcDNA3, available from Invitrogen (Carlsbad, Calif.); pBS vectors, Phagescript vectors, Bluescript vectors, pNH8A, pNH6a, pNH18A, pNH46A, available from Stratagene (La Jolla, Calif.); and ptrc99a, pKK223-3, pKK233-3, pDR540, pRIT5 available from Pharmacia (Peapack, N.J.). Among suitable eukaryotic vectors are pWLNEO, pSV2CAT, pOG44, pXT1, and pSG available from Stratagene (La Jolla, Calif.); and pSVK3, pBPV, pMSG and pSVL, available from Pharmacia (Peapack, N.J.).

A pTT vector backbone can be used for expressing the Cas polypeptide and/or sgRNA (Durocher et al., Nucl. Acids Res. 30:E9 (2002)). Briefly, the backbone of a pTT vector may be prepared by obtaining pIRESpuro/EGFP (pEGFP) and pSEAP basic vector(s), for example from Clontech (Palo Alto, Calif.), and pcDNA3.1, pCDNA3.1/Myc-(His)6 and pCEP4 vectors can be obtained from, for example, Invitrogen (Carlsbad, Calif.). As used herein, the pTT5 backbone vector can generate a pTT5-Gateway vector and be used to transiently express proteins in mammalian cells. The pTT5 vector can be derivatized to pTT5-A, pTT5-B, pTT5-D, pTT5-E, pTT5-H, and pTT5-I, for example. As used herein, the pTT2 vector can generate constructs for stable expression in mammalian cell lines.

A pTT vector can be prepared by deleting the hygromycin (Bsml and Sail excision followed by fill-in and ligation) and EBNA1 (Clal and Nsil excision followed by fill-in and ligation) expression cassettes. The ColEI origin (Fspl-Sall fragment, including the 3′ end of the β-lactamase open reading frame (ORF) can be replaced with a Fspl-Sall fragment from pcDNA3.1 containing the pMBI origin (and the same 3′ end of β-lactamase ORF). A Myc-(His)6 C-terminal fusion tag can be added to SEAP (Hindlll-Hpal fragment from pSEAP-basic) following in-frame ligation in pcDNA3.1/Myc-His digested with Hindlll and EcoPvV. Plasmids can subsequently be amplified in E. coli (DH5a) grown in LB medium and purified using MAXI prep columns (Qiagen, Mississauga, Ontario, Canada). To quantify, plasmids can be subsequently diluted in, for example, 50 mM Tris-HCl pH 7.4 and absorbencies can be measured at 260 nm and 280 nm. Plasmid preparations with A260/A280 ratios between about 1.75 and about 2.00 are suitable for producing the Fc-fusion constructs.

The expression vector pTT5 allows for extrachromosomal replication of the cDNA driven by a cytomegalovirus (CMV) promoter. The plasmid vector pCDNA-pDEST40 is a Gateway-adapted vector which can utilize a CMV promoter for high-level expression. SuperGlo GFP variant (sgGFP) can be obtained from Q-Biogene (Carlsbad, Calif.). Preparing a pCEP5 vector can be accomplished by removing the CMV promoter and polyadenylation signal of pCEP4 by sequential digestion and self-ligation using Sail and Xbal enzymes resulting in plasmid pCEP4A. A Gblll fragment from pAdCMV5 (Massie et al., J. Virol. 72:2289-2296 (1998)), encoding the CMV5-poly(A) expression cassette ligated in Bglll-linearized pCEP4A, resulting in the pCEP5 vector.

Additional vectors include optimized for use in CHO-S or CHO-S-derived cells, such as pDEF38 (CHEF 1) and similar vectors (Running Deer et al., Biotechnol. Prog. 20:880-889 (2004)). The CHEF vectors contain DNA elements that lead to high and sustained expression in CHO cells and derivatives thereof. They may include, but are not limited to, elements that prevent the transcriptional silencing of transgenes.

Vectors may include a selectable marker for propagation in a host. A selectable marker can allow the selection of transformed cells based on their ability to thrive in the presence or absence of a chemical or other agent that inhibits an essential cell function. Selectable markers confer a phenotype on a cell expressing the marker, so that the cell can be identified under appropriate conditions. Suitable markers include genes coding for proteins which confer drug resistance or sensitivity thereto, impart color to, or change the antigenic characteristics of those cells transfected with a molecule encoding the selectable marker, when the cells are grown in an appropriate selective medium.

Suitable selectable markers include dihydro folate reductase or G41 8 for neomycin resistance in eukaryotic cell culture; and tetracycline, kanamycin, or ampicillin resistance genes for culturing in E. coli and other bacteria. Suitable selectable markers also include cytotoxic markers and drug resistance markers, whereby cells are selected by their ability to grow on media containing one or more of the cytotoxins or drugs; auxotrophic markers, by which cells are selected for their ability to grow on defined media with or without particular nutrients or supplements, such as thymidine and hypoxanthine; metabolic markers for which cells are selected, for example, for ability to grow on defined media containing a defined substance, for example, an appropriate sugar as the sole carbon source; and markers which confer the ability of cells to form colored colonies on chromogenic substrates or cause cells to fluoresce.

Retroviral vectors are contemplated herein. One such vector, the ROSA geo retroviral vector, which maps to mouse chromosome six, was constructed with the reporter gene in reverse orientation with respect to retroviral transcription, downstream of a splice acceptor sequence (U.S. Pat. No. 6,461,864; Zambrowicz et al., Proc. Natl. Acad. Sci. 94:3789-3794 (1997)). Infecting embryonic stem (ES) cells with ROSA geo retroviral vector resulted in the ROSA geo26 (ROSA26) mouse strain by random retroviral gene trapping in the ES cells.

Adeno-associated viral vectors (AAV vectors) are contemplated herein. The term“adeno-associated virus” or “AAV” as used herein can refer to a member of the class of viruses associated with this name and belonging to the genus dependoparvovirus, family Parvoviridae. Multiple serotypes of this virus are known to be suitable for gene delivery; all known serotypes can infect cells from various tissue types. At least 11 or 12, sequentially numbered, are disclosed in the prior art. Non-limiting exemplary serotypes useful in the methods disclosed herein include any of the 11 or 12 serotypes, e.g., AAV2, AAV5, and AAV8, or variant serotypes, e.g. AAV-DJ. The AAV structural particle is composed of 60 protein molecules made up of VP1, VP2, and VP3. Each particle contains approximately 5 VP1 proteins, 5 VP2 proteins and 50 VP3 proteins ordered into an icosahedral structure.

AAV is a naturally occurring defective virus that requires another virus, such as an adenovirus or a herpes virus, as a helper virus for efficient replication and a productive life cycle. (For a review, see Muzyczka et al., Curr. Topics in Micro and Immunol. 158:97-129 (1992)). AAV vectors efficiently transduce various cell types and can produce long-term expression of transgenes in vivo. AAV vectors have been extensively used for gene augmentation or replacement and have shown therapeutic efficacy in a range of animal models as well as in the clinic; see, e.g., Mingozzi and High, Nature Reviews Genetics 12, 341-355 (2011); Deyle and Russell, Curr Opin Mol Ther. 2009 August; 11(4): 442-447; Asokan et al., Mol Ther. 2012 April; 20(4): 699-708. AAV vectors containing as little as 300 base pairs of AAV can be packaged and can produce recombinant protein expression. For example, AAV2, AAV5, AAV2/5, AAV2/8 and AAV2/7 vectors have been used to introduce DNA into photoreceptor cells (see, e.g., Pang et al., Vision Research 2008, 48(3):377-385; Khani et al., Invest Ophthalmol Vis Sci. 2007 September; 48(9):3954-61; Allocca et al., J. Virol. 2007 81(20):11372-11380). In some embodiments, the AAV vector can include (or include a sequence encoding) an AAV capsid polypeptide described in PCT/US2014/060163; for example, a virus particle comprising an AAV capsid polypeptide having an amino acid sequence selected from the group consisting of SEQ ID NOs: 1, 3, 5, 7, 9, 11, 13, 15, and 17 of PCT/US2014/060163, and a Cas sequence and capped-guide RNA sequence as described herein. In some embodiments, the AAV capsid polypeptide is an Anc80 polypeptide, e.g., Anc80L27; Anc80L59; Anc80L60; Anc80L62; Anc80L65; Anc80L33; Anc80L36; or Anc80L44. In some embodiments, the AAV incorporates inverted terminal repeats (ITRs) derived from the AAV2 serotype. Exemplary left and right ITRs are presented in Table 6 of WO 2018/026976 and are listed below:

It should be noted, however, that numerous modified versions of the AAV2 ITRs are used in the field, and the ITR sequences shown below are exemplary and are not intended to be limiting. Modifications of these sequences are known in the art, or will be evident to skilled artisans, and are thus included in the scope of this disclosure. Expression of the Cas polypeptide and/or sgRNA in the AAV vector can be driven by a promoter described herein or known in the art. In some embodiments, AAV vectors capable of delivering ˜4.5 kb are used for packaging of the nucleic acids encoding capped-sgRNAs or Cas polypeptides. In some embodiments, AAVs capable of packaging larger transgenes such as about 4.6 kb, 4.7 kb, 4.8 kb, 4.9 kb, 5.0 kb, 5.1 kb, 5.2 kb, 5.3 kb, 5.4 kb, 5.5 kb, 5.6 kb, 5.7 kb, 5.8 kb, 5.9 kb, 6.0 kb, 6.1 kb, 6.2 kb, 6.3 kb, 6.4 kb, 6.5 kb, 6.6 kb, 6.7 kb, 6.8 kb, 6.9 kb, 7.0 kb, 7.5 kb, 8.0 kb, 9.0 kb, 10.0 kb, 11.0 kb, 12.0 kb, 13.0 kb, 14.0 kb, 15.0 kb, or larger are used.

A DNA insert comprising nucleic acids (optionally contained in a vector or vectors) encoding Cas9 polypeptides or sgRNAs can be operatively linked to an appropriate promoter, such as the phage lambda PL promoter; the E. coli lac, trp, phoA, and tac promoters; the SV40 early and late promoters; and promoters of retroviral LTRs. Suitable vectors and promoters also include the pCMV vector with an enhancer, pcDNA3.1; the pCMV vector with an enhancer and an intron, pCIneo; the pCMV vector with an enhancer, an intron, and a tripartate leader, pTT2, and CHEF1. The promoter sequences include at least the minimum number of bases or elements necessary to initiate transcription of a gene of interest at levels detectable above background. Within the promoter sequence may be a transcription initiation site, as well as protein binding domains (consensus sequences) responsible for the binding of RNA polymerase. In alternative embodiments, eukaryotic promoters will often, but not always, contain “TATA” boxes and “CAT” boxes.

The expression constructs can further contain sites for transcription initiation, termination, and, in the transcribed region, a ribosome binding site for translation. The coding portion of the transcripts expressed by the constructs can include a translation initiating codon at the beginning and a termination codon (UAA, UGA, or UAG) appropriately positioned at the end of the polypeptide to be translated.

In some embodiments of the compositions and methods of the disclosure, the vector is or comprises an “RNA targeting system” comprising (a) nucleic acid sequence encoding an Cas polypeptide or dCas polypeptide or dCas polypeptide fusion protein; and (b) a capped-single guide RNA (capped-sgRNA) sequence comprising: an RNA sequence (or spacer sequence) that hybridizes to or binds to a target RNA sequence and an RNA sequence (direct repeat or scaffold sequence) capable of binding to or associating with the Cas polypeptide and wherein the RNA targeting system recognizes the target RNA and enhances translation of the target RNA. In some embodiments, the nucleic acid sequence or vector is a single vector.

Transfection of animal cells typically involves opening transient pores or “holes” in the cell membrane, to allow the uptake of material. There are various methods of introducing foreign DNA into a eukaryotic cell. Transfection can be carried out using calcium phosphate, by electroporation, or by mixing a cationic lipid with the material to produce liposomes, which fuse with the cell membrane and deposit their cargo inside. Many materials have been used as carriers for transfection, which can be divided into three kinds: (cationic) polymers, liposomes, and nanoparticles.

VII. Methods of Modulating Protein Translation

Some embodiments disclosed herein provide compositions for and methods of enhancing protein translation in a cell, comprising introducing capped-sgRNAs (e.g., any of the capped-sgRNAs described herein) and Cas polypeptides (e.g., any of the Cas polypeptides described herein) into the cell.

EXAMPLES

The following examples are provided to better illustrate the claimed invention and are not to be interpreted as limiting the scope of the invention. To the extent that specific materials are mentioned, it is merely for purposes of illustration and is not intended to limit the invention. One skilled in the art can develop equivalent means or reactants without the exercise of inventive capacity and without departing from the scope of the invention.

Example 1: Modulation of Translation Using dCas and Capped-sgRNA

Exemplary constructs for generating nuclease dead Cas (dCas13b) and m7G capped-sgRNA are shown in FIG. 1A. dCas and capped-sgRNA were transcribed from either the same promoter (i), or independent promoters (ii) by RNA polymerase II. An exemplary structure for the unprocessed capped-sgRNA is shown in FIG. 1B. From 5′ to 3′, the capped-sgRNA contains the m7G cap, a linker of variable length, a spacer, a direct repeat, an RNase P processing site such as a tRNA-like small RNA, and a poly-A tail. An exemplary chemical composition of a capped-sgRNA is shown in FIG. 1C. Variants of the m7G cap include either guanosine or adenine for the second nucleotide of the di-nucleotide m7G cap (at the a′ position). FIG. 1D shows RNase P processing to trim downstream sequences, including the poly-A tail, from the transcript. The capped-RNA complexed with dCas, binds to a site on the target messenger RNA thereby bringing the m7G cap of the sgRNA to the vicinity of a desired start codon (FIG. 1E).

A two construct system was used to test the ability of dCas and capped-sgRNA to regulate translation in trans. The first construct includes a dCas13b gene driven by a PGK promoter, followed by a NLS-Turquoise reporter which is driven by an EF1α promoter. The second construct includes a sequence encoding a capped sgRNA, a 5′UTR region of ATF4, and the ATF4 ORF linked to an NL-Citrine promoter. Both the sequence encoding a capped sgRNA and the ATF4 ORF are driven by a TRE promoter. The second construct further includes an rtTA-P2A-Puro construct linked to an NLS-Cherry reporter via an IRES sequence. The rtTA-P2A-Puro-IRES-NLS-Cherry portion is driven by the EF1α promoter. A number of different types of capped sgRNAs (sg(1), sg(2), sg(3), sg(4), sg(5), sg(6)) were generated, each included a spacer that targets the ATF4 transcript at a different site. The sequences of the sgRNAs are listed in below. The target sequences were within the “sgRNA targeting window” as shown in FIG. 1G. Control capped-sgRNAs were also generated that do not target a sequence within the ATF4 transcript. These control capped-sgRNAs are referred to as non-targeting sgRNAs. Each capped-sgRNA was tested using dCas gradient in combination with a target ATF4 transcript gradient. The plots in FIG. 1H reflect log 2 fold difference in Citrine/Cherry ratio between each capped sgRNA—sg (a1), sg(a2), sg(a3), sg(a4), sg(a5) and sg(a6), and non-targeting sgRNAs. A spacer targeting a region just 3′ proximal to the start codon AUG was shown to result in the biggest increase in protein expression. The results demonstrate that optimal translational control is a function of the target sequence chosen, the expression level of the target RNA, and the expression level of dCas.

Uncapped-sgRNAs that correspond to each of the capped-sgRNA tested were subjected to the same gradient test. As shown in FIG. 1I, uncapped-sgRNAs were either ineffective in enhancing translation, or only minimally enhanced translation. These results showed that the localized recruitment of the 5′ m7G cap proximal to a start codon enabled an enhancement in translation.
